I am lost!

My application form runs OK in my system but not other systems. I even try and make a simple
form eg, like just have user input of a name and a submit button. It runs OK in my system but not other desktops or cell phones ??HELP!!

Ignore this post. I have found out my own mistake. Reason it failed was when I created a data collection I did not set it to a form submission. But at the same time it wasn’t clearly show I have to set it up.
